electroretinograph (ERG)

A test that measures how well the retina is working. During this test, you will wear a sensor on your eye to measure the electrical activity at the back of your eye on your retina. This test is used to diagnose inherited retinal diseases, as well as measure of the progression of retinal disease. As photoreceptors die, electrical activity on the retina decreases.
